Details

ESET SSL (Secure socket layer) scanning is a feature that allows or denies network communications based on a system of certificates that legitimate web services use to identify themselves. In some cases, a legitimate web service or network device might be denied by ESET SSL scanning because its certificate changes frequently, or it does not use an SSL certificate. You can create exceptions to SSL scanning in ESET Windows home products that will allow communications with these services or devices.

Solution

I. Enable Pre-release updates

II. Create an SSL scanning exception for the service or device
 

I. Enable Pre-release updates

Enabling pre-release updates will allow your ESET product to receive any recent changes to the SSL scanning module, which might resolve a conflict you are having with a service or device.

  1. Open the main program window of your ESET Windows product.

  2. Press the F5 key to access Advanced setup.
     
  3. Click Update and expand Profiles → Basic. Select Pre-release update
